"The man died as a result of police action, but we cannot give more details of the incident," he said.

"Reports of a farmer being killed by a mob of farmworkers in the province are not true. Those allegations are false."

Ipid spokesman Moses Dlamini said an investigator was on his way to the scene where the protester was shot to get more details.

"I can confirm that one person was killed. However we only have a report that three were injured. An investigator is on his way to gather more details."

Joemat-Pettersson said her state security and police counterparts, Siyabonga Cwele and Nathi Mthethwa, would "engage further in the matter".

"To give information now [on the death] would be very clumsy and irresponsible," she said.

A notice indicating the intent to call all interested parties to comment on the sectoral determination would be published by next Friday.

"I would also like to call on all the parties that have been involved in the current negotiations in the farms in the Western Cape to intensify their effort to resolve the current impasse," Oliphant said in a statement.

"The negotiations and the resolution should be pursued over and above the other efforts like re-looking at the sectoral determination, which process may take a while to conclude."

Joemat-Pettersson said the sectoral determination could only be revised once a year.

A revisal would affect all farmworkers across the country, regardless of produce. – Sapa
